Buzz box project

Let's build buzz boxes, drone synths, noise machines, whatever you want to call them.

I've ordered a bunch of components I think will be useful for building such devices, mostly gleaned from schematics and projects I've found online.
The two main sources of sound I can make with these are Reverse Avalanche Mode (RAM) Oscillators and 555 Oscillators.
For shaping, we can build simple RC filters or the legendary MS20 filter
And for modulation, we're going to build a bunch of vactrols (LED strapped to a photodiode), although we might need to use some OpAmps to boost the voltage sent to the LEDs if we're running them off of the RAM oscillators.

Future plans

  1. Learn to build gear so that I can pivot my career
  2. Prepare the Drone Day workshop at Feral Vector
  3. Make a drone album entirely from hand-built DIY junk
  4. Get rich / Die trying

Parts

As mentioned, I ordered a bunch of junk: Mouser order for Buzz Box 0.0
